I was looking on the Weber site. Confusing. Way too many options. I ended up emailing them for their recommendations. I was given two options. There must be one specific speaker type that was used in the mid 60's by Fender on the PR that these manufacturers make. The codes are there. Why make it so complicated? That in itself is a total turn off. If someone is trying to find an accurate replacement, they're not going to be doping the speaker, and most us don't know how many hz those speakers were in 64/65. They're also pricey, almost double for a similar speaker by Eminence.
